Answer for Stored Procedures with an output parameter Exercise

Hi Mark!

Thanks for reaching out and pointing this out!

Quite simply, to not complicate the code and the task, we let the procedure apply to non-duplicate records only (in terms of combination of first and last names).

You can add a GROUP BY first_name clause to solve for this problem.

Hope this helps.
Best,
Martin
